Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a roll brush suitable for cleaning objects having unevenness or grooves, such as iron plates for grilled meat.

<Conventional technology> Cleaning work requires a lot of effort and time, and in recent years,
Mechanization of cleaning work is progressing in various industrial fields. However, if the object to be cleaned has unevenness or grooves, such as an iron plate for grilling, the roll brush built into the cleaning device is prone to wear and tear, so brushes made of wear-resistant materials are used. However, roll brushes with sufficient durability have not been obtained, and this has become an impediment to the widespread use of cleaning devices.

<Problems to be solved by the invention> When a conventional roll brush is used on an object to be cleaned that has unevenness or grooves, it is necessary to bring the roll brush close to the object to be cleaned so that the tip of the brush reaches into the recess or groove. As a result, the brush was subject to severe bending and impact at the flat or convex portions, easily fell down, and was prone to wear and breakage. In particular, the brush wires often break from the base, and the broken brush wires scatter as if shot and may pierce the human body, posing a safety problem.

<Means for the invention to solve the problem> Therefore, the present invention includes a rotating shaft, a long strip of brush support that is provided around the rotating shaft and rotates around the rotating shaft while receiving rotational force from the rotating shaft. , a brush fixed to the support and having bristles extending in a radial direction with respect to the rotating shaft, the brush being formed by a plurality of brush bundles continuous in the longitudinal direction of the brush support, Each brush bundle is formed by folding the center of a plurality of brush bristles in half, and the folds sandwich a long strip common to each brush bundle serving as a core on the inside, and this long strip from the outside. It is formed by winding a substantially C-shaped channel material of each bundle around a swollen part as the center, while the support body has a fitting groove parallel to the rotation axis, and the fitting groove is The inside of the groove has a cylindrical space extending parallel to the rotation axis, and the elongated strip is bridged between the centers of both bottom surfaces of the cylindrical space, and at the same time, the base of each brush bundle is inserted into the cylindrical space. An object of the present invention is to provide a roll brush that is rotatably received in the inner circumferential direction of a long strip body.

<Function> The roll brush of the present invention alleviates the bending and impact at the flat part or convex part by attaching the brush so that it can be rotated or rocked, and on the other hand, the brush's beating effect increases cleaning efficiency. It is characterized by:

<Example> Hereinafter, embodiments will be described based on the figures.

FIG. 1 is a perspective view of the roll brush 1. FIG. The roll brush 1 includes circular support plates 3, 3 in which the supports of the brush 4 are located near both ends of the rotating shaft 2, and a plurality of support shafts 5 installed at equal intervals between the support plates 3, 3. 5, 5, and a large number of brushes 4, 4, . . . shown in FIG. 3 are rotatably attached to the support shafts 5, 5, 5.

The brush 4 has a brush bundle 4a wrapped around a short tube 6 in a single layer and bent at the center, and a substantially horseshoe-shaped locking ring 7 is fitted to the bent portion of the brush bundle 4a. By inserting the support body 5 into the brush 4, the brush 4 becomes rotatable.

In the roll brush 1, the rotation of the brush 4 is restricted when the distance between the support plates 3, 3 is narrowed, and on the other hand, the rotation of the brush 4 is restricted when the distance is widened. By making fine adjustments, the degree of freedom of rotation of the brush 4 can be adjusted as appropriate.

The brush 14 shown in FIG. 4 is the brush 4, 4...
The brush bundles 4a, 4a, . . . groups are fixed to a long tube (not shown) in place of the short tube 6 by a locking ring 17 having a substantially horseshoe-shaped cross section.

Next, FIG. 5 shows an embodiment in which the brush 4 is swingable, which is the main purpose of the present invention. FIG. 5 shows the state in which the support plates at both ends have been removed, and fitting grooves 25, 25, 25 corresponding to the support shafts 5, 5, 5 are bored at equal intervals on the peripheral edge of the support cylinder 23. The fitting groove 25 has brushes 4, 4 shown in FIG.
...A group or brushes 14 shown in FIG. 4 are fitted. The fitting groove 25 and the locking rings 7, 17 of the brushes have an arcuate cross section close to a circle, and the brushes 4, 14 are rotatable within the range of the opening 25a of the fitting groove 25. Incidentally, instead of the short tube 6 or the long tube of the brushes 4 and 14, a solid core may be used.

<Effects of the invention> As described above, the roll brush according to the invention is durable because the rotation or swinging of the brush alleviates the bending of the brush and the impact on the brush, preventing the brush from buckling or breaking. This improves safety and performance, and is especially suitable for cleaning objects with uneven surfaces or grooves where the brush is subject to severe wear.

Furthermore, even if the retaining ring 7 of the brush bundle is damaged, the base of the brush bundle is wound around the short tube 6 and is received in the fitting groove that has a cylindrical space inside, so that the brush bundle can be immediately removed. Prevent from falling off.
